I heard the real explanation later. The strongest dogs had been commandeered for the army, and these brave dogs of Flanders, who have always laboured, are now drawing _mitrailleuses_, as I saw them at L----. The little dogs must be fed, and there is no food to spare. And so the children, over whose heads passes unheeded the real significance of this drama that is playing about them, have their own small tragedies these days. We got into the car again and it moved off. With every revolution of the engine we were advancing toward that sinister line that borders No Man's Land. We were very close. The road paralleled the trenches, and shelling had begun again. It was not close, and no shells dropped in our vicinity. But the low, horizontal red streaks of the German guns were plainly visible. With the cessation of the rain had begun again the throwing over the Belgian trenches of the German magnesium flares, which the British call starlights. The French call them _fusées_. Under any name I do not like them. One moment one is advancing in a comfortable obscurity. The next instant it is the Fourth of July, with a white rocket bursting overhead. There is no noise, however. The thing is miraculously beautiful, silent and horrible. I believe the light floats on a sort of tiny parachute. For perhaps sixty seconds it hangs low in the air, throwing all the flat landscape into clear relief. I do not know if one may read print under these _fusées_. I never had either the courage or the print for the experiment. But these eyes of the night open and close silently all through the hours of darkness. They hang over the trenches, reveal the movements of troops on the roads behind, shine on ammunition trains and ambulances, on the righteous and the unrighteous. All along the German lines these _fusées_ go up steadily. I have seen a dozen in the air at once. Their silence and the eternal vigilance which they reveal are most impressive. On the quietest night, with only an occasional shot being fired, the horizon is ringed with them. And on the horizon they are beautiful. Overhead they are distinctly unpleasant. "They are very uncomfortable," I said to Captain F----. "The Germans can see us plainly, can't they?" "But that is what they are for," he explained. "All movements of troops and ammunition trains to and from the trenches are made during the night, so they watch us very carefully." "How near are we to the trenches?" I asked. "Very near, indeed." "To the first line?" For I had heard that there were other lines behind, and with the cessation of the rain my courage was rising. Nothing less than the first line was to satisfy me. "To the first line," he said, and smiled.
